Method and apparatus for selecting public land mobile-communication network for network access

Abstract

The embodiments of the invention provide a method and an apparatus for selecting public land mobile-communication network (PLMN) for network access. The method comprises the following steps that: home service equipment carries out statistics on the number of UE with access to a first PLMN; and according to the number of UE with access to the first PLMN and a preset rule, the home service equipment sends a notification message, thereby notifying the state of the first PLMN or an available PLMN to the UE. According to the embodiments of the invention, when the number of UE with access to the first PLMN exceeds a threshold value or the number of UE with access to the first PLMN exceeds the threshold value and the network state information of the PLMN is abnormal, the home service equipment or a machine type communication (MTC) service platform can notify the UE that the access to the PLMN is restricted currently, so that the UE can select other PLMN access; therefore, it is realized that access to a network through the available PLM by a user can be effectively controlled when there is a network problem on the PLMN or it is necessary to satisfy a requirement of a current PLMN network.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to a method and device for selecting a public land mobile communication network to access the network. Background technique [0002] M2M (machine to machine, machine to machine) is a machine to machine wireless communication. In a broad sense, M2M includes the following three modes: machine-to-machine, machine-to-mobile phone (such as user remote monitoring), mobile phone-to-machine (such as user remote control). [0003] With the widespread application of mobile technologies, the number of M2M terminals will account for an increasing proportion of the total number of terminals. The M2M business model may be in the form of MVNO (Mobile Virtual Network Operate, mobile virtual network operation), or may be operated by an operator of MNO (Mobile Network Operate, mobile network operation). In the MVNO mode, one of the possible networking methods is...

Problems solved by technology

Therefore, in the prior art, when network problems such as congestion or network failure occur in the network corresponding to the PLMN currently used by the M2M user, the M2M user only selects the network according to the priority of the PLMN ID and the strength of the wireless signal of the network corresponding to the PLMN. The PLMN ID obtained may still be the PLMN ID that has a network problem, so that it cannot access the network normally.
